- babypuncher 2y ago880 tons of nuclear fuel sounds like a typo. Radioactive debris, sure, but not melted fuel.
- joha4270 2y agoIt sounds a little high, but not massively so. I couldn't find fuel weight in a BWR-3, but a RBMK reactor (Chernobyl) contains between 150 and 200 tons of Uranium. Now, a RBMK runs natural uranium, so you're going to be using more fuel for the same power, but it suggests the number isn't totally whack. I would not be surprised by it being a typo, but depending on what you include in "melted fuel" (fuel assembly, reactor parts, etc), 880 tons isn't outrageously high either.
- egorfine 2y agoWell, ~75 tons of fuel per three units fully loaded plus a few times that for the spent nuclear fuel pools. Also bear in mind that fuel being melted with concrete and metal becomes one, so you can add a hefty multiplier to the above figure. So it seems like 800 tons is in the ballpark of the fuel assemblies plus molten metal structures of the lower part of the reactors vessels.
